Try Best Practices Analyzer to see if it flags something that can possibly be fixed and thus possibly making your error code go away. Other than that, start Googling/Binging the error code and do things articles tell you till it's gone.

Because Outlook 2007+ uses web services not just for OWA or Outlook Anywhere. It uses it for OOF, Free/Busy, OAB, Autodiscover, etc… The entire article already explains this and why you need to set the InternalURLs properly. Basically, I have already answered your question in my article as to why the InternalURLs need to match the name of the certificate.

Hi guys,
i have very similar problem, but only with internal access of my outlook clients.
Everythings from outside network (internet) working fine, outlook anywhere, activesync to mobile devices, outlook web access … nothing have problem.

But when my outlook clients trying to connect from local area network to the CAS server, i have the warning with certificate error.
The same i have warning with certificate, if i am trying to access outlook web access.

I have set all ways, directories etc in fight way. External things are to server.domain.com, internal things points to server.domain.local.
SSL certificate is signed by STARTSSL CA, which is trusted CA from public and it points to server.domain.com name.

So i can understand, why outlook clients have problems, if they trying to connect from local area network, because SSL certificate is pointing to another name of server? But why they are using SSL for connection, i have them inside company network, i dont need to use RPC over HTTPS for them. Maybe the problem is, my server have only one IP address, have all exchange roles together on one machine …?

Thank you for any kind of tips

With regards, Radek
